Crystals grown from concentrated solutions

Using powder as a starting material, single crystals were grown from a solution of hydrofluoric acid containing appropriate concentrations of each type of compound (M = K or Rb), using the slow cooling method [206, 209, 211,438],... 

The GaN substrates grown from nitrogen solution in pure gallium possess a high free-electron concentration of about 5 x 1019 cm 3 (if doped with magnesium, crystals are insulating [4]). This... 

Single crystals were grown from aqueous solution (i), methanol (ii, iii, iv) or methyltetrahydrofuran (v), Copper(ll) was introduced as a substantial impurity by growing single crystals from solutions containing a few percent of the corresponding copper complex. The estimated concentration of copper in the single crystals was about one percent. 

Figure 8 Dissolution-time profile of acetaminophen crystals (75 mg, 355-500 pm) in water at 4°C. The crystals were grown at 30°C and at 240 rpm from aqueous solutions containing initially 23.1 g/dm3 acetaminophen and the following concentrations of p-acet-oxyacetanilide a ( ) Zero ( ) 100 mg/dm3 (A) 300 mg/dm3 (O) 500 mg/dm3.
